众所周知,多晶立方氮化硼可转位刀片的规格尺寸受到限制,因为多晶立方氮化硼刀片的制造较困难。但目前西德一厂家已能成功的应用大尺寸的多晶立方氮化硼可转位刀片,该种刀片的直径为40毫米。厚度为8毫米,体积约为10厘米~3。下面例举一加工实例:用10毫米的吃刀量,一次加工形状和表面不规则的轧辊毛坯。这种轧辊是由Duplex—Nironite— As we all know, polycrystalline cubic boron nitride indexable blade size is limited, because polycrystalline cubic boron nitride blade manufacturing more difficult. However, a factory in West Germany has succeeded in using a large-size polycrystalline cubic boron nitride indexable insert, which has a diameter of 40 mm. Thickness of 8 mm, the volume is about 10 cm ~ 3. Here is an example of a processing example: With 10 millimeters to eat a knife, a rough shape and irregular surface roll blank. This roll is made of Duplex-Nironite-
